The Rams haven't heard from running back Tre Mason in 7 months, and the team is starting to get worried

Los Angeles Rams running back Tre Mason has not yet reported for mandatory team training camp, and on Monday head coach Jeff Fisher said that the team is worried about the 22-year-old's well-being.

"I haven't personally spoken with Tre since the season ended," Fisher told the media, according to CBS Sports. "I tried numerous times to reach him. Tre has made a decision not to communicate with us, not to talk. Not talking to his teammates. Right now we're more concerned about Tre Mason's well-being than we are his football career."

In March, Mason was tasered by police and arrested on charges of reckless driving, marijuana possession, and resisting arrest. According to TMZ, he has allegedly had four encounters with police in the last five months.

Deadspin notes that, during the most recent encounter with police on July 23, Mason's mother said that her son was "acting unusual."
